Title: Printing head
IPC: B41J2/28
Filed: 1992-03-10
Abstract: PURPOSE:To provide a printing head which is capable of generating a compact powerful magnetic circuit and performing hammer drive action efficiently. CONSTITUTION:A magnetic assembly consisting of paired core members 22, 23, 27, 28, permanent magnets 24, 29 sandwiched between these core members and solenoid coils 25, 26, 30, 31 wound around each core member, arranged from the vertical center and the lower half of the yoke 21 of a printing head. In addition, the N and S magnetic poles of a top permanent magnet and a bottom permanent magnet are arranged so that these magnetic poles are mutually at an opposite position. The same polarities react against each other at the border between both magnetic assemblies, thus preventing a magnetic flux from leaking out. Consequently, a highly efficient magnetic circuit is formed, and an armature is perfectly attracted by the magnetic action of a permanent magnet as a powerful attractive force.

Title: Optical fiber preform and production thereof
Inventor: KANAMORI HIROO
IPC: C03C13/04
Filed: 1987-03-09
Abstract: PURPOSE:To obtain an optical fiber preform suitable for the production of a dispersed shaft fiber having step-wise refractive index distribution and decreased transmission loss, by using GeO2-SiO2 as inner core, SiO2 as outer core and F-SiO2 as clad part. CONSTITUTION:Glass material for core and glass material for clad corresponding to each of the above compositions are produced by subjecting a soot produced by VAD process to the addition of F, dehydration and conversion to transparent glass material. The glass material for clad composed of F-SiO2 is bored to form a glass pipe for clad. If necessary, the glass material for core and/or glass material for clad are drawn. The glass material for core is inserted into the hollow part of the glass pipe for clad and is integrated by heating. Since the obtained optical fiber preform has decreased content of transmission loss deteriorating factor having absorption in ultraviolet range by the addition of F to the inner core and the outer core, the preform is highly effective in reducing the transmission loss of an optical fiber when used as a preform for a step-wise dispersed shaft fiber.

Filed: 1985-03-18
Abstract: PURPOSE:To control the primary current by inputting a compensating element relative to the primary frequency to the primary current control system, thereby maintaining the response of a control system constant irrespective of the primary frequency. CONSTITUTION:A gain compensator 8 for varying the output of an adder 5 in response to the primary frequency command is provided between the adder 5 and an amplifier 9.

The primary current is altered in response to the deviation, thereby controlling the primary voltage in response to the command value.

Title: Driving device for moving iron core type linear compressor
Inventor: HIROSE KENJI
IPC: F04B35/04
Filed: 1982-03-30
Abstract: PURPOSE:To prevent a mechanical break-down by supplying current from a temperature detecting circuit through a control circuit to a control coil to avoid an excessive stroke of a piston even in high temperature of the atmosphere. CONSTITUTION:In low temperature of the atmosphere, a transistor 21 is turned off so that a normally opened contact 22a of a relay 22 is opened. In high temperature of the atmosphere, the transistor 21 is turned on and the contact 22a of the relay 22 is closed so that direct current is supplied to a controlling coil 11 which acts as a direct current magnet. Thus an attraction acts on a controlling moving iron core 12 before and after a stroke of a piston to control the stroke in the direction of reducing the stroke. Thus, a mechanical breakdown can be prevented.
